Aloe Vera Rescue: Repotting, Soil, Light, and Watering

Saving an Overpotted Aloe with Moldy Soil

A newly purchased aloe in a 1-gallon pot (possibly 3 plants) developed surface mold after a week with 10–12 oz water. The pot is too large, and standard potting soil holds too much moisture.

Immediate Repotting (Do It Now)

1. Use cactus/succulent mix (or 1:1 potting soil + coarse sand/perlite).
2. Choose a pot same size or slightly smaller (6" diameter for 1-ft plant). Shallow is fine—aloe roots are near the surface.
3. Ensure drainage hole.
4. Gently remove plant, shake off old soil (minimize root disturbance).
5. Repot in fresh mix; do not water for 3–5 days to let any root wounds callous.

Light

Place in the sunniest window (south, west, or east) with direct sun for several hours daily. African violet light is insufficient.

Watering

• Water only when soil is bone dry and pot feels light.
• Summer: every 7–10 days. Winter: every 2–3 weeks.
• Water thoroughly, drain completely.
• Better underwater than overwater—aloes rot fast.

Mold on Soil

Surface mold indicates excessive moisture. It will disappear with correct soil, pot, and watering.

Aloes thrive on neglect: sun, sandy soil, rare water.
